如何在imagepicker中设置imagepicker.tag=value

Question

我是iphone sdk的新手，当我设置imagepicker.tag=vaule(100)时，它会产生一个错误，所以有人能帮我解决这个问题吗？

   `  imagepicker=[[UIImagePickerController alloc]init];
    imagepicker.delegate=self;
    imagepicker.sourceType=UIImagePickerControllerSourceTypePhotoLibrary;
    [self presentModalViewController:imagepicker animated:YES];`

Answer 1

imagepicker=[[UIImagePickerController alloc]init];
imagepicker.sourceType=UIImagePickerControllerSourceTypePhotoLibrary;
[self presentModalViewController:imagepicker animated:YES];
imagepicker.view.tag = 100;

Answer 2

tag是UIView的属性。UIImagePickerController是UIViewController的一个子类。它没有tag属性。
